The FCC just posted documents for a curious Sprint-branded case called the ZTE Peel 3200, packing its own battery and EV-DO connectivity as well as mobile hotspot capabilities. It might be for heroically transforming your iPod Touch into a phone.

Apparently the Peel doesn't physically connect to the device it's slipped around, which has the folks at PhoneScoop surmising that it could be designed to connect to the iPod Touch over Wi-Fi, allowing it to make calls on Sprint's 3G network. The Peel also has the ability to serve as a Wi-Fi hotspot for 5 devices.

PhoneScoop points out that the name itself could be a further clue for deciphering its mysterious function: it would allow you to "peel" away from AT&T's iDevice hegemony. That's good. Maybe even a little bit too good? But the real question here: would the additional bulk be worth the freedom from the AT&T ball and chain? [FCC via PhoneScoop via BGR]
